Clinical trials play an important role in advancing medicine, helping researchers evaluate the safety and effectiveness of new treatments, therapies, and medical devices. However, for decades, many populations have been underrepresented in clinical research, including members of the LGBTQ+ community. While conversations about the importance of inclusion continue to grow, researchers are also recognizing the need for clinical trials to better reflect the diverse populations they are intended to serve.
Here’s a look at why LGBTQ+ representation in clinical trials is critical to improving outcomes in often-underserved communities.
Clinical trials help researchers determine whether a treatment is safe and effective before it becomes widely available. To generate meaningful results, study participants should reflect the populations that may eventually use those treatments. When certain groups are excluded or underrepresented, researchers may have limited information about how treatments affect those communities.
When clinical trials are diverse, researchers can better understand differences in health outcomes, identify potential disparities, and ensure findings are applicable to a broad range of patients. Inclusive research is an important step toward improving health equity and building trust between researchers and the communities they serve.

For many years, there has been a lack of LGBTQ+ representation in clinical trials. Several factors have contributed to discrimination within healthcare settings, including concerns about privacy, limited outreach to LGBTQ+ communities, and the lack of routine collection of sexual orientation and gender identity data in research.
Historical experiences of stigma and exclusion have also contributed to distrust of medical institutions among some LGBTQ+ individuals. As a result, many patients may be unaware of research opportunities or hesitant to participate. According to clinical researcher Joyce H.N. Nortey, MPH, MSBH, Sr. Director, Clinical Research & Operations at Evidation Health and Research Advisor for the Fibroid Foundation, “trust is not something researchers can assume — it has to be earned through transparency, consistency, and respect.” These barriers can make it difficult for researchers to fully understand the health needs and experiences of LGBTQ+ populations.
Increasing LGBTQ+ participation in clinical trials can help researchers gain a more complete understanding of how treatments, therapies, and healthcare interventions affect diverse populations. Greater representation can also help identify health disparities, improve patient outcomes, and ensure research findings are relevant to the communities most impacted by certain conditions.
For Jordan J. Edwards, the Deputy Director at the BQ+ Center for Liberation of the Normal Anomaly Initiative and a participant in a Phase 2 clinical trial evaluating Broadly Neutralizing Antibodies alongside long-acting Lenacapvir treatment for HIV, participation was about more than his own healthcare journey.
“About two weeks after my diagnosis, I came to terms with the fact that not only could I live, but most importantly, that I wanted to live,” Edwards said. “I’m a person of faith, and I believe there’s a reason for living and a higher purpose in helping others. I wanted to do what I could to be a part of something that could support others and potentially contribute to a cure for HIV. As a Black man participating in a major health study, it felt like an opportunity to help change what’s possible for others someday.”
He also hopes his participation helps reduce stigma and distrust surrounding clinical research.
“I could reduce the distrust around clinical studies for other Black, Brown, and queer communities, allowing for a partnership based on trust and representation to grow,” he said.
As healthcare continues to evolve, inclusive participation in clinical trials remains essential. Whether the research focuses on HIV or other health conditions, representation helps ensure scientific discoveries benefit all communities.
Creating more inclusive clinical trials requires intentional efforts from researchers, healthcare providers, and study sponsors. One important step is ensuring recruitment materials and outreach strategies reflect diverse communities and are accessible to LGBTQ+ individuals.
Building partnerships with trusted community organizations and healthcare providers can also help increase awareness about clinical trial opportunities and foster trust among potential participants.
Nortey says researchers should also avoid viewing communities as a single uniform group. Instead, understanding participants’ individual experiences, motivations, and concerns can help create more inclusive and participant-centered research environments.
Additionally, researchers can improve inclusion by collecting data on sexual orientation and gender identity when appropriate, training staff in culturally competent care, and creating study environments where participants feel respected and affirmed. Edwards encouraged LGBTQ+ individuals who may be hesitant about participating in research to ask questions and seek information before making a decision.
“If you are hesitant to be a part of a trial, first recognize that it is valid to feel that way,” he said. “If you don’t understand the process, ask for clarity until you understand. Once you dig deep to get your questions that influence hesitancy, you can then make an informed decision. You have a voice and a choice of what works best for you.”
